--- Comment #30 from Adrian Chadd <adrian@freebsd.org> ---
I hacked on the negotiation bits after reading the spec.

The spec mandates SBC, but the initial config fetch doesn't return SBC. It's
returning some non-mandatory codec. I'm not sure if we have to ask it anoth=
er
way or not.

I overrode some things, and it fails the set_configuration call, but the
headset makes the "i'm ready!" noise. So something's happening.

^C

I'll read the error values back from the call soon and see what's going on.
